Bosc's fringe-toed lizard
Bosc's fringe-toed lizard is a medium-sized lizard endemic to North Africa and Western Asia, distinguished by its olive-grey coloration with dark longitudinal stripes and fringed digits on its feet. This fast-moving and active forager inhabits diverse environments, including coastal plains, cultivated areas, saltmarshes, oases, and wadis, typically where vegetation cover is moderate on sandy or gravelly substrates. Males are territorial and generally larger than females, with reproductive success influenced by size, and females carry clutches of eggs whose number depends on abdominal capacity.

About Bosc's fringe-toed lizard
Bosc's fringe-toed lizard (Acanthodactylus boskianus), also known by the variant name Bosk's fringe-fingered lizard, is a species of lizard belonging to the Lacertidae family. This species is native to a wide range across North Africa and Western Asia. It is characterized by its medium size, with a snout-to-vent length typically between 5 and 8 cm, and males are generally larger than females. A distinctive feature of this lizard is its feet, which possess long, slender digits fringed for efficient movement.
Description and Habitat
The dorsal surface of Bosc's fringe-toed lizard is typically olive-grey, marked by five longitudinal dark stripes, with the central stripe notably subdividing at the neck. Its underside is whitish, though females may develop a red suffusion on the underside of their tails during the breeding season. Juveniles are identifiable by their blue tails. The species thrives in a variety of habitats, including coastal plains, cultivated areas, saltmarshes, oases, and wadis, usually preferring locations with moderate vegetation cover on sandy or gravelly substrates. Its distribution spans numerous countries, including Algeria, Egypt, Iran, Iraq, Syria, and Saudi Arabia.
Behavior and Reproduction
Bosc's fringe-toed lizard is known for its speed and active foraging behavior. Males exhibit territoriality, with larger individuals often being more successful. Evidence suggests that chemical cues present in the skin and exudate from femoral glands play a role in chemical communication, aiding in sex recognition and courtship rituals. This species is oviparous, meaning it reproduces by laying eggs. Females typically lay clutches of around four eggs, with the number potentially ranging from two to seven, influenced by the female's abdominal capacity.
